How can we obtain in coloured component from blue or black ink
Answers
The blue ink (or black ink) used; in fountain pens is a liquid mixture. It is a mixture of a dye in water. This dye is the colored component of the ink (which gives it a blue or black color). We can separate the colored component of ink (or dye from ink) by the process of evaporation.

No, the dye in black ink is not a single colour. We can justify this statement by performing the process of chromatography. In this process the solutions are separated of the coloured substances. It is mostly used in the forensic labs.
